摘　　要：针对目前环境性能污染排放指标存在的缺点,本文推导了基于系统输出能量的输出基准排放因子,利用输出基准排放因子能够方便的计算出系统的污染总排放量。考虑到与分产系统相比,联产系统的环境效益,本文引入了余热回收环境效益法,通过与PSI(污染减排率指标)比较,认为余热回收环境效益法适合评估联产系统取代集中式供能系统对当地环境的影响,而PSI适合评估全球范围的环境影响。The existing environmental performance indexes have drawbacks, so output-based emission factor was derived, and it＇ s easy to calculate the total emissions. Taking into account the environmental benefit due to cogeneration, the method of the ＂Heat Recovery Benefit＂ proposed in this study is suitable for a local-scale environmental impact evaluation as a proper approach compared with PSI （Pollutant Saving Index）. Moreover, the method of PSI value is suitable to estimate the global-scale environmental impact.
